SYNOPSIS

        # Let SNMP::Info determine the correct subclass for you.
        my $l1 = new SNMP::Info(
                                 AutoSpecify => 1,
                                 Debug       => 1,
                                 DestHost    => 'myswitch',
                                 Community   => 'public',
                                 Version     => 1
                               )
           or die "Can't connect to DestHost.\n";

        my $class = $l1->class();
        print "SNMP::Info determined this device to fall under subclass : $class\n";

        # Let's get some basic Port information
        my $interfaces = $l1->interfaces();
        my $i_up       = $l1->i_up();
        my $i_speed    = $l1->i_speed();

        foreach my $iid (keys %$interfaces) {
           my $port  = $interfaces->{$iid};
           my $up    = $i_up->{$iid};
           my $speed = $i_speed->{$iid}
           print "Port $port is $up. Port runs at $speed.\n";
        }

DESCRIPTION

       This class is usually used as a superclass for more specific device classes listed under
       SNMP::Info::Layer1::*   Please read all docs under SNMP::Info first.

       Provides abstraction to the configuration information obtainable from a Layer1 device
       through SNMP.  Information is stored in a number of MIBs.

       For speed or debugging purposes you can call the subclass directly, but not after
       determining a more specific class using the method above.

        my $l1 = new SNMP::Info::Layer1(...);

   Required MIBs
       SNMP-REPEATER-MIB

       MIBs required for "Required MIBs" in SNMP::Info

       See "Required MIBs" in SNMP::Info for its MIB requirements.

       SNMP-REPEATER-MIB needs to be extracted from ftp://ftp.cisco.com/pub/mibs/v1/v1.tar.gz

GLOBALS

       These are methods that return scalar value from SNMP

       $l1->ports_managed()
           Gets the number of ports under the interface mib

           ("ifNumber")

   Overrides
       $l1->model()
           Cross references $l1->id() with product IDs.

           For HP devices, removes 'hpswitch' from the name

           For Cisco devices, removes 'sysid' from the name

       $l1->vendor()
           Tries to discover the vendor from $l1->model() and $l1->vendor()

       $l1->ports()
           Adds the values from rptr_ports() and ports_managed()

       $l1->slots()
           Number of 'groups' in the Repeater MIB

           ("rptrGroupCapacity")

   Global Methods imported from SNMP::Info
       See documentation in "GLOBALS" in SNMP::Info for details.

TABLE METHODS

       These are methods that return tables of information in the form of a reference to a hash.

   Overrides
       $l1->interfaces()
           Returns reference to the map between IID and physical Port.

       $l1->i_up()
           Returns reference to map of IIDs to link status.

       $l1->i_up_admin()
           Returns reference to map of IIDs to administrative link status.

   Repeater MIB
       $l1->rptr_ports()
           Number of ports in each group.

           ("rptrGroupPortCapacity")

       $l1->rptr_port()
           Port number in Group

           ("rptrPortIndex")

       $l1->rptr_slot()
           Group (slot) Number for given port.

           ("rptrPortGroupIndex")

       $l1->rptr_up_admin()
           ("rptrPortAdminStatus")

       $l1->rptr_up()
           ("rptrPortOperStatus")

       $l1->rptr_last_src()
           ("rptrAddrTrackNewLastSrcAddress")
